About LongevityLab
LongevityLab is an independent resource for evidence-based training, sleep, and healthspan practices. Free tools, no paywalls, no affiliate commissions on content.
Our companion iPhone apps
The site is operated by the developers of three iOS apps: Zone 2 Longevity Coach (Zone 2 cardio), Aurnia (sleep tracking with explanations), and Repvy (5/3/1 strength logger). The free tools here work standalone — the apps add ongoing tracking and personalization.
Editorial standards
Articles are drafted with AI assistance, reviewed, and cite peer-reviewed sources (PubMed, NEJM, JAMA, peer-reviewed sports science journals) for clinical claims.
Who this site is for
LongevityLab is built for general readers who want practical, evidence-aware guidance on aerobic conditioning, lifting, sleep quality, and long-term health habits without sifting through dense research papers first.
